Description
About the Product
The Tripper MCB 25A TP 415V AC 6kA C Curve is a high-performance Miniature Circuit Breaker engineered for protection of three phase electrical systems against overload & short circuit faults. It is ideal for industrial & commercial applications where moderate to high current loads & inductive equipment are present.
With a 25A current rating & a 6kA breaking capacity, this MCB ensures safe & efficient interruption of fault currents. The triple pole (TP) configuration allows simultaneous protection & isolation of all three phases, ensuring balanced & reliable system safety. The C Curve tripping characteristic makes it suitable for circuits with moderate inrush currents such as motors, pumps, compressors, & other inductive loads.
How the Mechanism Works
This MCB provides dependable circuit protection through continuous monitoring & rapid tripping:
• Continuously monitors current across all three phases
• Trips when overload conditions exceed safe limits
• Instantly disconnects supply during short circuit faults
• Allows moderate inrush currents without nuisance tripping
• Simultaneously isolates all three phases
This ensures safe, stable, & efficient operation of three phase electrical systems.
